Make Background Service run on startup as well as every minute

Currently, I have a IntentService that checks a php server for new notifications intended for the user, and a BroadcastReceiver that listens for BOOT_COMPLETED. What I wanna know is how do I combine to two to not only make the IntentService run on startup, but also make the IntentService run every minute from that point.

Also, I want to make sure that I'm sending notifications the right way. In IntentService.onHandleIntent(), I have this for sending the notification.

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this).setSmallIcon(R.mipmap.ic_launcher).setContentTitle(title).setContentText(message);
NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(Integer.parseInt(id), mBuilder.build());

Am I missing anything for this to actually create the notification? (The variables "title", "message", and "id" are already set)

Use AlarmManager for repeated tasks.

// Setup a recurring alarm every half hour
  public void scheduleAlarm() {

    // Construct an intent that will execute the AlarmReceiver
    Intent intent = new Intent(getApplicationContext(), MyAlarmReceiver.class);

    // Create a PendingIntent to be triggered when the alarm goes off
    final PendingIntent pIntent = PendingIntent.getBroadcast(this, MyAlarmReceiver.REQUEST_CODE,
        intent, PendingIntent.FLAG_UPDATE_CURRENT);

    // Setup periodic alarm every 5 seconds
    long firstMillis = System.currentTimeMillis(); // alarm is set right away

    AlarmManager alarm = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE);

    // First parameter is the type: ELAPSED_REALTIME, ELAPSED_REALTIME_WAKEUP, RTC_WAKEUP
    // Interval can be INTERVAL_FIFTEEN_MINUTES, INTERVAL_HALF_HOUR, INTERVAL_HOUR, INTERVAL_DAY
    alarm.setInexactRepeating(AlarmManager.RTC_WAKEUP, firstMillis,
        AlarmManager.INTERVAL_HALF_HOUR, pIntent);
  }

For Detailed explanation refer https://guides.codepath.com/android/Starting-Background-Services#using-with-alarmmanager-for-periodic-tasks.

In every onReceive call of MyAlarmReceiver you can start your intentservice. You should also read https://developer.android.com/training/scheduling/alarms.html
